ADDUCTS CONTAINING ISOCYANATE GROUPS AND COMPOSITION ADHERING EFFECTIVELY TO PAINTED SUBSTRATES.

摘要

The present invention relates firstly to adducts of the formula (I) which are obtainable from the reaction of an oligomeric aliphatic polyisocyanate and a compound of the formula HX-R<1>. Secondly the invention relates to one-component or two-component compositions which comprise such adducts of the formula (I). The adducts of the formula (I) find a use as adhesion promoters and are suitable in particular for use in elastic adhesives and sealants. The cured one-component or two-component compositions exhibit excellent paint adhesion in tandem with high extensibility.
